ROBERT HEARNS, OF ST. PAUL, MINNESOTA. v

NoN-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent N o. 742,985, dated November 3," 1903.

Application led March 10,1903. Serial No. 147,073. (No model.)

nesota, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

My invention relates to improvements in non-rellable bottles of that construction in which the valve is normally held in closed position by a weight, but which will permit the liquid to pass from the bottle when the bottle is held in pouring position and which will prevent refilling of the bottle.

In the accompanying drawings, forming part of this specilication, Figure 1 is a longitudinal cross-section of the bottle embodying my features of invention. Fig. 211s a view of the plug forming part of the closing means. Fig. 3 is a top view of a spring forming part of my invention. Fig. 4 is a view of a valveplug closing the bottom of the bottle-neck, and Fig. 5 is a view of a valve-disk which cooperates with said plug.

In the drawings, A represents abottle. The lower portion of the bottle-neck is formed with an inwardly-inclined shoulder 2, forming a seat for the tapering valve-plug 3, a washer 4 being interposed between the plug and seat- The washer 4 is of relatively soft material, so as io constitute a tight joint even though there be small irregularities in the plug or bottle-neck. The valve-plug 3 is formed witha series of openings 5. Said plug is also formed with a central opening 6, through which passes a cord 7, supporting at its lower end a weight 8 and secured at its upper end to a disk 9, preferably of cork, which normally covers the openings 5. The disk 9 is provided with a series of peripheral grooves 10, forming openings to allow the liquid to pass from `the openings 5 around the disk when the parts are in the positions shown in dottedline in Fig. 1. The upper end of the bottle-neck is closed by a plug l1, normally held in closing position by an irregularshaped spring 12, which. fits in a groove 13 in the plug and projects into a groove 14 in the bottle-neck. The groove 13 communicates with the space below the plug 1l by the opening 15 and with the space above the plug by be emptied by being turned into inverted position. When'the bottle is turned into inverted position, the liquid will pass through the openings in the valve-plug, carrying the disk 9 tothe dotted-line position shown, and

passing around said disk and through the openings in the upper plug 11. When the bottle is in upright position, the weight 8 will hold the disk 9 in contact with the top of the valve-plug, closing the openings-5 and preventing any liquid being forced into the bottle. The spring 17, interposed between the two plugs, will hold the lower or valve plugiirmly upon its seat.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with the neck of a bottle formed at its lower end with an inwardlybeveled shoulder, a valve-plug seated upon said shoulder and formed with a series of openings, a disk loosely arranged upon said tion of said bottle-neck and provided with a 3.
